woon-sHArING DEVICE.

Application filed April 19, 1923. Serial No. 633,189.

My said invention relates to a wood shaping device for shaping parts such as the ends of wooden handles for hammers, to fit them to the eye of the hammer or other tool. Ordinarily very little shaping is done in the factory where the handles are made on account of the time required and because the shaping cannot be done accurately. My invention enables a lathe operator to do this work quickly and accurately while also tending the lathe in which the handlesare turned. The device is simple and compact and can be placed on or near the lathe so that while one handle is being turned in the lathe another can have its end shaped to fit in the eye of a hammer. In the case of tools such as hammers where the eye is oblong two separate units are required for shaping the part of the handle that fits in the eye but for other handles a. single unit may suffice.

Referring to the accompanying drawing which is made a part hereof and on which similar reference characters indicate similar parts the figure shows a side elevation of my device partly in section to indicate the construction of the disks.

In the drawing reference character 10 in dicates a base suported on any suitable foundation and having a pair of spaced upwardly extending arms terminating in bearings 11 in which is supported a shaft 12 driven by a pulley 13. At each end the shaft is reduced in diameter as shown at 1 to form a shoulder. A reinforcing disk 15, which in this instance ismade of metal is located against said shoulder this being followed by a wooden disk 16 reduced toward its outer periphery and faced with sandcloth or equivalent material 17 which extends over the edges of the wooden disk and is folded over so as to be clamped at its outer edges between the two disks.

A spacer 21 is interposed between disks 16 and 18, the latter being also faced with abrasive material 19 and being backed by a reinforcing disk 20. The outer extremity of the shaft is threaded and a nut 22 thereon serves to force all the parts into close engagement with each other and against the shoulder on the shaft.

A similar construction appears at the other end of the shaft where reinforcing disks 16 and 20 support abrasive material 17' and 19', a spacer 21 similar to that shown at 21 but of greater length being interposed between the disks which are held in place against a shoulder on the shaft 12 by a nut 22.

In the operation of my device the shaft is driven by a belt passing over the pulley 13 and a hammer handle or like object is in serted' between the disks at one end of the shaft. Assuming that the longer sides of the handle bars to be finished first it will be inserted between disks 16 and 18, a rest such as is ordinarily used in lathes being provided for supporting the handle during the shaping operation. The abrasive material at the opposite sides of the handle will cut down both sides equally andthe sleeve 18 will automatically stop the operation when a sufficient amount has been removed, due to the handle striking. against the sleeve. It will be seen that each of the opposed disks acts as a gage for the operation of the other whereby a proper amount of material will be removed from each face and that due to their conjoint action such removal will be equal, or substantially so, on each of the opposed faces which act conjointly asa centering device. When the longer sides have been finished the handle is inserted between the disks at the opposite end of the shaft,

it being turned so as to bring the shorter sides against the abrasive faces. The same operation is then repeated, the action of the disks being stopped by the striking of the end of the handle against the sleeve 21'.

In case the eye of the tool is square only a single pair of disks will be required.

It will be evident to those skilled in the art that my device may be modified in various ways and used for various purposes,

consequently I do not limit myself to the specific mechanism shown in the drawin s and described in the specification but on y as indicated in the appended claim.

Having thus fully described my'said invention, what. I claim as new and desire to secure byLetters Patent, is:

A shaping device for wooden handles comprising a shaft, power transmission means associated with said shaft, a pair of bevel faced woodendisks mounted on said shaft with the bevels turned toward each other, an abrasive sheet covering the bevel faces of each disk, a sleeve for holding said disks separated in fixed spaced relation and serving as V a stop for work operated upon, a pair of fiat metal reinforcing back plates for said Wooden disks, and means on said shaft asthe ends of the sleeve and the wooden disks, sociated with said reinforcing plates for substantially as set forth. 10 binding them against said Wooden disks and In witness whereof, I have hereunto set the wooden disks against said sleeve, the my hand at Indianapolis, Indiana, this 16th outer edges of said abrasive sheets being day of April, A. D. nineteen hundred and clamped between the contiguous faces of the twenty-three' disks and reinforcing plates, and the central portion of said sheets being'clamped between WILLIAM T. MOLAUGHLIN.
